Qwen2.5-1.5B-Open-R1-SFT-1_full

Model Card for Qwen2.5-1.5B-Open-R1-SFT-1_full

This model is a fine-tuned version of Qwen/Qwen2.5-1.5B-Instruct on the presencesw/en_processed_open-s1 dataset. It has been trained using TRL.

Quick start

from transformers import pipeline

question = "If you had a time machine, but could only go to the past or the future once and never return, which would you choose and why?"
generator = pipeline("text-generation", model="presencesw/Qwen2.5-1.5B-Open-R1-SFT-1_full", device="cuda")
output = generator([{"role": "user", "content": question}], max_new_tokens=128, return_full_text=False)[0]
print(output["generated_text"])
